OSHA PEL for crystalline silica in the form of quartz is = 10 mg/m 梅 (% SiO2+2) , and 50% of this value for
crystobalite and tridymite.
SECTION III - HEALTH HAZARD and FIRST AID INFORMATION
CHRONIC HAZARDS:
Primary Route of Exposure: Inhalation
Exposure Limits: (Acceptable exposure levels for this product must be defined in the workplace due to the
combination of silica and other constituents and condition of use.) Unless specified otherwise, limits are
expressed as eight-hour time-weighted averages (TWA). Limits for cristobalite and tridymite (other forms of
cyrstalline silica) are equal to one-half of the limits for quartz.

classified; OSHA PEL.= 15 mg/m (total particulate, not otherwise regulated). OSHA PEL = 5 mg/m (respirable
particulate, not otherwise regulated).

Respirable Crystalline Silica (quartz): TLV = 0.1 mg/m ; OSHA PEL =10 mg/m 梅 (%SiO2 +2); OSHA Proposed

Respirable Dust containing silica: OSHA PEL = 10 mg/m 梅 (%SiO2 + 2)

Total Dust containing silica: OSHA PEL = 30 mg/m 梅 (%SiO2 + 2)
ACGIH and OSHA have determined that adverse effects are not likely to occur in the workplace provided
exposure levels do not exceed the appropriate TLVs/PELs. However, because of the wide variation in individual
susceptibility, lower exposure limits may be appropriate for some individuals, including persons with pre-existing
medical conditions such as those described below.

Abbreviations: TLV = threshold limit value of the American Conference of Governmental Industrial Hygienists
(ACGIH); OSHA PEL = permissible exposure limit of the Occupation Safety and Health Administration (OSHA);

mg/m = milligrams of substance per cubic meter of air.
SUBCHRONIC AND CHRONIC HEALTH EFFECTS:
Pulmonary Diseases: Excessive exposure to particulates (dust) over an extended period of time may result in the
development of silicosis and other pulmonary diseases.
Carcinogenicity: IARC has classified respirable crystalline silica (quartz) a known carcinogen in humans.
California Proposition 65 Warning: Ground dry clay products will expose you to respirable crystalline silica
which is 鈥渒nown in the State of California to cause cancer and to other substances which are known to the State of
California to cause cancer, birth defects and other reproductive harm.鈥?
See also: American Society for testing and Materials (ASTM) Standard practice E1132-86, 鈥淪tandard Practice for
Health Requirements Relating to Occupational Exposure to Quartz Dust.鈥?
Medical Conditions Aggravated by Exposure: Excessive dust exposure may aggravate any existing respiratory
disorders or diseases. Possible complications of allergies resulting in irritation to skin, eyes and respiratory
passage may occur from excessive exposure to dusts.
ACUTE HAZARDS:
Eye Contact: Direct contact with dust may cause irritation by mechanical abrasion.
Skin Contact: Direct contact may cause irritation by mechanical abrasion.
Skin Absorption: Not expected to be a significant exposure route.
Ingestion: Expected to be practically non-toxic. Ingestion of large amounts may cause gastrointestinal irritation
and blockage.
Inhalation: Dusts may irritate the nose, throat, and respiratory tract by mechanical abrasion. Coughing, sneezing,
and shortness of breath may occur following exposures in excess of appropriate exposure limits. Use of natural
sand and gravel for construction purposes is not believed to cause additional acute toxic effects. However,
repeated overexposure to very high levels of respirable crystalline silica (quartz, cristobalite, tridymite) for periods
as short as six months have caused acute silicosis. Acute silicosis is a rapidly progressive, incurable lung disease
that is typically fatal. Symptoms include (but are not limited to); shortness of breath, cough, fever, weight loss, and
chest pain.
FIRST AID:
Eyes: Immediately flush eye(s) with plenty of clean water for at least 15 minutes, while holding the eyelid(s) open.
Occasionally lift the eyelid(s) to ensure thorough rinsing. Beyond flushing, do no attempt to remove material from
the eye(s). Contact a physician if irritation persists or later develops.
Skin: Wash with soap and water. Contact a physician if irritation persists or later develops.
Ingestion: If person is conscious, give large quantity of water and induce vomiting; however, never attempt to
make an unconscious person drink or vomit. Get immediate medical attention.
Inhalation: Remove to fresh air. Dust in throat and nasal passages should clear spontaneously. Contact a
physician if irritation persists or later develops.

SECTION VII - PERSONAL PROTECTION AND CONTROL MEASURES
RESPIRATORY PROTECTION: To minimize exposure to dust and/or crystalline silica, wet the clay. When such
controls are not feasible, NIOSH/MSHA approved respirators must be worn in accordance with a respiratory
protection program, which meets OSHA requirements as set forth at 29 CFR 1910.134 and ANSI Z88.2-1080
鈥淧ractices for Respiratory Protection.鈥?
SKIN PROTECTION: Use gloves and/or protective clothing if abrasion or allergic reactions are experienced.
EYE PROTECTION: Use safety glasses with side shields. Face shields should also be used when dry sawing
clay products. Dust goggles should be worn when excessively (visible) dusty conditions are present or are
anticipated.
LOCAL EXHAUST: When grinding clay products, use sufficient local exhaust to reduce the level of respirable
dust to the applicable standards set forth in Section III. See ACGIH 鈥淚ndustrial Ventilation, A Manual of
Recommended Practice,鈥? latest edition.
SAFETY MEASURES: Wear safety goggles, hard hats and/or steel-toed safety shoes when bagging these
products.
WORK/HYGIENIC PRACTICES: Avoid creating and breathing dust.
OTHER CONTROL MEASURES: Respirable dust and quartz levels should be monitored regularly. Dust and
quartz levels in excess of appropriate exposure limits should be reduced by feasible engineering controls,
including (but not limited to) wet sanding, wet suppression, ventilation, and process enclosures. Respirators must
be worn when such controls are not feasible or do not completely control dust generation.
SECTION VIII - HANDLING AND STORAGE INFORMATION
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Use adequate ventilation dustless
vacuum or cleanup systems for handling, storage, and clean-up so that airborne dust does not exceed the PEL.
Use adequate ventilation and dust equipment. Practice good housekeeping. Do not permit dust to collect on
walls, floors, sills, ledges, machinery, or equipment. Maintain, clean, and fit test respirators in accordance with
OSHA standards. Maintain and test ventilation and dust collection equipment. Wash or vacuum clothing which
has become dusty. See also control measures in Section VII.
WASTE DISPOSAL METHOD: This material is classed as a non-hazardous solid waste for disposal.
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORING: This product is not intended or designed for use
as an abrasive blasting medium or for foundry applications and should not be used for those purposes. Do not
store near food and beverages or smoking materials.
